While Koenigsegg was busy making the 1,340-hp One:1, the owner of this normal Agera R was plotting a coup against the mother company by making his car more powerful than the highly publicized Megacar. This juicy red Agera R has 1,400 horsepower!

YouTubist Marchettino was lucky enough to be invited for a ride in this Koenigsegg Agera R  and his filmed it in action. To be really honest with you, it is hard to see why the owner has bothered with gaining the extra 400 horses. The performance difference between 1,000 and 1,400 is not as big as you think.

To achieve 1,400 horsepower, this Agera R benefits from more extreme turbochargers, which of course entails more modifications to the car’s electronic brain, cooling system, and exhaust. The other thing this treatment brings is a mahoosive bill!
